Abstract
Background: Associations of the strength of school smoking policies with
cigarette, e-cigarette and cannabis use in Wales were examined. Methods:
Nationally representative cross-sectional survey of pupils aged 11–16 years
(N=7376) in Wales. Senior management team members from 67
schools completed questionnaires about school smoking policies, substance use
education and tobacco cessation initiatives. Multi-level, logistic regression
analyses investigated self-reported cigarette, e-cigarette and cannabis use, for all
students and those aged 15–16 years. Results: Prevalence of
current smoking, e-cigarette use and cannabis use in the past month were 5.3%,
11.5% and 2.9%, respectively. Of schools that provided details about
smoking policies (66/67), 39.4% were strong (written policy applied to
everyone in all locations), 43.9% were moderate (written policy not applied to
everyone in all locations) and 16.7% had no written policy. There was no
evidence of an association of school smoking policies with pupils’ tobacco or
e-cigarette use. However, students from schools with a moderate policy [OR =
0.47; 95% (confidence interval) CI: 0.26–0.84] were less likely to have
used cannabis in the past month compared to schools with no written policy. This
trend was stronger for students aged 15–16 years (moderate policy: OR =
0.42; 95% CI: 0.22–0.80; strong policy: OR = 0.45; 95% CI:
0.23–0.87). Conclusions: School smoking policies may exert less
influence on young people’s smoking behaviours than they did during times of
higher adolescent smoking prevalence. Longitudinal studies are needed to examine the
potential influence of school smoking policies on cannabis use and mechanisms
explaining this association.

Abstract
The standard Yee algorithm is widely used in computational electromagnetics because of its simplicity and divergence free nature. A generalization of the classical Yee scheme to 3D unstructured meshes is adopted, based on the use of a Delaunay primal mesh and its high quality Voronoi dual. This allows the problem of accuracy losses, which are normally associated with the use of the standard Yee scheme and a staircased representation of curved material interfaces, to be circumvented. The 3D dual mesh leapfrog-scheme which is presented has the ability to model both electric and magnetic anisotropic lossy materials. This approach enables the modelling of problems, of current practical interest, involving structured composites and metamaterials.

Abstract
OBJECTIVE The objective of this systematic review was to evaluate existing studies on the effectiveness of percutaneous endoscopic gastrostomy (PEG) feeding compared to nasogastric (NG) feeding for patients with non-stroke related dysphagia. METHODS We searched Ovid MEDLINE, EMBASE, the Cochrane Library, Web of Science and PubMed databases through to December 2013 using the terms "percutaneous endoscopic gastrostomy", "gastrostomy", "PEG", "nasogastric", "nasogastric tube", "nasogastric feeding" and "intubation". We included randomized controlled trials (RCTs) and non-RCTs which compared PEG with NG feeding in individuals with non-stroke dysphagia. RESULTS 9 studies involving 847 participants were included in the final analysis, including two randomized trials. Pooled analysis indicated no significant difference in the risk of pneumonia [relative risk (RR) = 1.18, 95% confidence interval (CI) = 0.87-1.60] and overall complications [relative risk (RR) = 0.80, 95% confidence interval (CI) = 0.63-1.02] between PEG and NG feeding. A meta-analysis was not possible for mortality and nutritional outcomes, but three studies suggested improved mortality outcomes with PEG feeding while two out of three studies reported PEG feeding to be better from a nutritional perspective. CONCLUSIONS Firm conclusions could not be derived on whether PEG feeding is beneficial over NG feeding in older persons with non-stroke dysphagia, as previously published literature were unclear or had a high risk of bias. A well-designed and adequately powered RCT, which includes carer strain and quality of life as outcome measures is therefore urgently needed.

Abstract
For two decades the search for genes involved in Alzheimer's disease brought little reward; it was not until the advent of genome-wide association studies (GWAS) that genetic associations started to be revealed. Since 2009 increasingly large GWAS have revealed 20 loci, which in itself is a substantial increase in our understanding, but perhaps the more important feature is that these studies have highlighted novel pathways that are potentially involved in the disease process. This commentary assembles our latest knowledge while acknowledging that the casual functional variants, and undoubtedly, other genes are still yet to be discovered. This is the challenge that remains and the promise of next-generation sequencing is anticipated as there are a number of large initiatives which themselves should start to yield information before long.

Abstract
The solar neighbourhood is the closest and most easily studied sample of the Galactic interstellar medium, an understanding of which is essential for models of star formation and galaxy evolution. Observations of an unexpectedly intense diffuse flux of easily absorbed 1/4-kiloelectronvolt X-rays, coupled with the discovery that interstellar space within about a hundred parsecs of the Sun is almost completely devoid of cool absorbing gas, led to a picture of a 'local cavity' filled with X-ray-emitting hot gas, dubbed the local hot bubble. This model was recently challenged by suggestions that the emission could instead be readily produced within the Solar System by heavy solar-wind ions exchanging electrons with neutral H and He in interplanetary space, potentially removing the major piece of evidence for the local existence of million-degree gas within the Galactic disk. Here we report observations showing that the total solar-wind charge-exchange contribution is approximately 40 per cent of the 1/4-keV flux in the Galactic plane. The fact that the measured flux is not dominated by charge exchange supports the notion of a million-degree hot bubble extending about a hundred parsecs from the Sun.

Abstract
BACKGROUND The extent to which different symptom dimensions vary according to epidemiological factors associated with categorical definitions of first-episode psychosis (FEP) is unknown. We hypothesized that positive psychotic symptoms, including paranoid delusions and depressive symptoms, would be more prominent in more urban environments. METHOD We collected clinical and epidemiological data on 469 people with FEP (ICD-10 F10-F33) in two centres of the Aetiology and Ethnicity in Schizophrenia and Other Psychoses (AESOP) study: Southeast London and Nottinghamshire. We used multilevel regression models to examine neighbourhood-level and between-centre differences in five symptom dimensions (reality distortion, negative symptoms, manic symptoms, depressive symptoms and disorganization) underpinning Schedules for Clinical Assessment in Neuropsychiatry (SCAN) Item Group Checklist (IGC) symptoms. Delusions of persecution and reference, along with other individual IGC symptoms, were inspected for area-level variation. RESULTS Reality distortion [estimated effect size (EES) 0.15, 95% confidence interval (CI) 0.06-0.24] and depressive symptoms (EES 0.21, 95% CI 0.07-0.34) were elevated in people with FEP living in more urban Southeast London but disorganized symptomatology was lower (EES -0.06, 95% CI -0.10 to -0.02), after controlling for confounders. Delusions of persecution were not associated with increased neighbourhood population density [adjusted odds ratio (aOR) 1.01, 95% CI 0.83-1.23], although an effect was observed for delusions of reference (aOR 1.41, 95% CI 1.12-1.77). Hallucinatory symptoms showed consistent elevation in more densely populated neighbourhoods (aOR 1.32, 95% CI 1.09-1.61). CONCLUSIONS In people experiencing FEP, elevated levels of reality distortion and depressive symptoms were observed in more urban, densely populated neighbourhoods. No clear association was observed for paranoid delusions; hallucinations were consistently associated with increased population density. These results suggest that urban environments may affect the syndromal presentation of psychotic disorders.

Abstract
OBJECTIVE The objective of this study is to assess clinical variables that may be associated with risk for opioid misuse in individuals with chronic pancreatitis. DESIGN This study utilized a descriptive, quasi-experimental, cross sectional design. SETTING AND PATIENTS Three hundred seven individuals with nonalcoholic chronic pancreatitis engaged in chronic opioid therapy for pain presented to an outpatient specialty clinic at an academic medical center. MEASURES Participants completed the Current Opioid Misuse Measure (COMM), Brief Pain Inventory (BPI), Short Form (SF)-12 Quality of Life Measure, Center for Epidemiological Studies 10-item Depression Scale (CESD), and a single item asking about current alcohol use. Mean scores on the CESD, COMM, BPI, SF-12, and factors associated with opioid misuse measures from regression analyses were the outcome measures. RESULTS Mean scores on the CESD, COMM, BPI pain-on-average item, and the SF-12 physical and psychological quality of life factors (t scores) were 11.2 (standard deviation [SD] = 6.7), 8.5 (SD = 7.3), 4.8 (SD = 2.8), 39.7 (SD = 7.0), and 45 (SD = 9.0), respectively. Descriptive analyses revealed that 55% of participants scored above the clinical cutoff for depression on the CESD, and 39% scored above the cutoff for opioid misuse concerns on the COMM. Regression analyses identified several factors associated with higher opioid misuse measure scores, including increased depressive symptoms from the CESD (β = 0.38, P < 0.0001), increased pain rating at the time of the office visit (β = 0.16, P = 0.03), impairment of psychological quality of life (β = -0.27, P = 0.001) and endorsement of alcohol use (β = 0.16, P = 0.03). These factors accounted for 37% of the variance in current opioid misuse scores. CONCLUSIONS Depression, quality of life, pain intensity and alcohol use may be good candidate variables for prospective studies to determine clinical risk factors for opioid misuse among patients with pancreatitis.

Abstract
Eleven susceptibility loci for late-onset Alzheimer's disease (LOAD) were identified by previous studies; however, a large portion of the genetic risk for this disease remains unexplained. We conducted a large, two-stage meta-analysis of genome-wide association studies (GWAS) in individuals of European ancestry. In stage 1, we used genotyped and imputed data (7,055,881 SNPs) to perform meta-analysis on 4 previously published GWAS data sets consisting of 17,008 Alzheimer's disease cases and 37,154 controls. In stage 2, 11,632 SNPs were genotyped and tested for association in an independent set of 8,572 Alzheimer's disease cases and 11,312 controls. In addition to the APOE locus (encoding apolipoprotein E), 19 loci reached genome-wide significance (P < 5 × 10(-8)) in the combined stage 1 and stage 2 analysis, of which 11 are newly associated with Alzheimer's disease.

Abstract
X-ray spectra following charge exchange collisions between C6+ and He are presented for collision energies between 460 eV/u and 32,000 eV/u. Spectra were obtained at the Oak Ridge National Laboratory Multicharged Ion Research Facility using a microcalorimeter X-ray detector capable of fully resolving the C VI Lyman series lines through Ly-γ. These line ratios are sensitive to the initial electron l-distribution and test our understanding of the charge exchange process. In addition, these line ratios are important for identifying charge exchange in astrophysical contexts involving the interaction of solar wind ions with neutrals. Our measurements are performed at collision velocities (300 km/s to 2500 km/s) which overlap most of the solar wind range. Additional data of this type can be combined with computations to provide an extensive set of reliable line ratios and absolute cross sections for the interpretation of a variety of astrophysical situations.

Abstract
Previous studies have shown that total pancreatectomy with islet cell autotransplantation improves quality of life in chronic pancreatitis. A significant number of these patients develop postoperative hyperglycemia and daily insulin requirements or increase in daily insulin requirements. Our study investigates whether increased insulin requirements postoperatively have a negative impact on quality of life. A prospectively collected database of 74 patients undergoing extensive pancreatectomy with islet autotransplantation for pancreatitis was reviewed. Data pertaining to daily requirements and quality of life (QOL), as measured by the SF-12 questionnaire, in the preoperative and postoperative period were reviewed. Approval from the Institutional Review Board for the evaluation of human subjects was obtained. Seventy-four patients underwent extensive pancreatectomy with islet autotransplantation for pancreatitis. The majority of these patients required new daily insulin or an increase in daily insulin requirements post-operatively. Mean preoperative HA1c in this group was 5.6 with an increase to 7.3 at 6 months postoperatively ( P < 0.001), a mean of 8.1 at 12 months, and 8.9 at 2 years. Mean preoperative daily insulin requirements for this group were five units/day with average increase to 19 units/day at 6 months, 21 units/day at 12 months, and 26 units/day at 2 years. Preoperative QOL scores were a mean of 26 for the physical component and 36 for the mental health component. Postoperatively, physical component scores averaged 33 at 6 months (p < 0.001), 36 at 12 months, and 36 at 2 years; the mental health component scores averaged 42 at 6 months (p = 0.007), 41 at 12 months, and 41 at 2 years.

Abstract
Previous studies have shown that total pancreatectomy with islet cell autotransplantation improves quality of life in chronic pancreatitis. A significant number of these patients develop postoperative hyperglycemia and daily insulin requirements or increase in daily insulin requirements. Our study investigates whether increased insulin requirements postoperatively have a negative impact on quality of life. A prospectively collected database of 74 patients undergoing extensive pancreatectomy with islet autotransplantation for pancreatitis was reviewed. Data pertaining to daily requirements and quality of life (QOL), as measured by the SF-12 questionnaire, in the preoperative and postoperative period were reviewed. Approval from the Institutional Review Board for the evaluation of human subjects was obtained. Seventy-four patients underwent extensive pancreatectomy with islet autotransplantation for pancreatitis. The majority of these patients required new daily insulin or an increase in daily insulin requirements postoperatively. Mean preoperative HA1c in this group was 5.6 with an increase to 7.3 at 6 months postoperatively (P < 0.001), a mean of 8.1 at 12 months, and 8.9 at 2 years. Mean preoperative daily insulin requirements for this group were five units/day with average increase to 19 units/day at 6 months, 21 units/day at 12 months, and 26 units/day at 2 years. Preoperative QOL scores were a mean of 26 for the physical component and 36 for the mental health component. Postoperatively, physical component scores averaged 33 at 6 months (p < 0.001), 36 at 12 months, and 36 at 2 years; the mental health component scores averaged 42 at 6 months (p = 0.007), 41 at 12 months, and 41 at 2 years. There is no correlation between physical component score or mental component score QOL scores and daily insulin requirements (r = -0.016 and r = 0.039, respectively). Total pancreatectomy with islet cell autotransplantation is an effective surgery for end-stage chronic pancreatitis. Quality of life significantly improves in physical and mental health components regardless of a postoperative increase in daily insulin requirements.
